Red Queen

The Red Queen is a specialty weapon designed by the Order of the Sword. Its handle resembles a motorcycle accelerator, twisting the Red Queen's grip releases a powerful propellant along the edge of the sword. The explosive force of this propellant can turn even the weakest person into an agent of destruction.However, this power has been seen as a upgrade due to modifications conducted by Nero, making it impossible for the untrained to handle.

The Red Queen is Nero's only melee weapon - as a new character this opposes Dante's regular selection of at least 3 different melee weapons while Red Queen is Nero's only regular Devil Arm.

Gameplay
Nero can execute a few interesting combo moves using Red Queen. Aside from that, he can also "charge" his sword using a gauge called EX-gauge. When fully charged, the sword will release streaks of crimson flame/energy around it. However, unlike Dante's drive, the charged EX-gauge increase the sword's attack damage and distance.

Trivia

 * In Resident Evil, also produced by Capcom, there was a computer with AI, named the Red Queen. It is believed that the sword was given its name as a reference to this.
 * Watching the animations in-game actually reveals Nero is only capable of weilding Red Queen with one arm as his other is in possetion of the Devil Bringer.
